Abstract
The invention discloses a silica gel keystroke and a formation method thereof. The silica gel keystroke comprises a keystroke basal body and keystroke characters arranged on the surface of the keystroke basal body. The keystroke characters and the keystroke basal body are all made of silica gel and are molded to be integral through heat pressing. The formation method includes the following steps: a), processing a keystroke die which has a first die cavity and at least one second die cavity arranged at the bottom of the first die cavity; b) infusing the liquid silica gel into the second die cavity; c), putting solid silica gel into the first die cavity; and d), combining the liquid silica gel and the solid silica gel through heat pressing. In this way, a silica gel keystroke can be made. By combining the liquid silica gel and the solid silica gel through heat pressing to make the silica gel keystroke, the invention is high in processing efficiency and simple in process. The silica gel keystroke is wear-resistant and reduces the costs on manpower and material resources and ensures the quality of the silica gel keystroke. Molded from liquid silica gel through heat pressing, the keystroke characters on the silica gel keystroke are more wear-resistant.

Embodiment
As shown in Figure 1 to Figure 3, the forming method of a kind of silica gel push-button of present embodiment is to be used for the moulding silica gel push-button, this silica gel push-button 1 is made up of button matrix 11 and at least one button character 12 of being located at button matrix surface 111, this forming method comprises the steps: a) processing button mould, second die cavity of the forming press key character at the bottom of this button mould has first die cavity of forming press key matrix and is located at this first die cavity chamber, the quantity of this second die cavity is consistent with the button character quantity of each silica gel push-button, each die cavity is all by the electrode discharge moulding, and carry out blasting treatment, stick on the mould when the demoulding with the silica gel push-button that prevents forming; B) liquid-state silicon gel is injected each second die cavity of mould, the color of liquid-state silicon gel is chosen according to the color of button character, and the liquid level of the liquid-state silicon gel in each second die cavity will be lower than 0.05mm～0.1mm at the bottom of the chamber of first die cavity; C) solid-state silica gel is put into first die cavity; D) with this mould pressing and forming under hot press, after hot pressing, the liquid-state silicon gel that injects second die cavity becomes one with the solid-state silica gel of putting into first die cavity, forms needed silica gel push-button.When hot-forming, pressure is controlled at 100～150kg, and temperature is controlled at 170 ℃, and hot pressing time was generally 110 seconds, and concrete molding parameter is according to parameters such as the thickness decision of mould size, silica gel push-button.
To shown in Figure 7, this silica gel push-button has button matrix 11 and protrudes five button character 12 of this button matrix surface 111 as Fig. 2.When making the button mould, 43,44,45,46,47, five second die cavities 43,44,45,46,47 of five second die cavities of 42 are used for five button character of moulding at the bottom of processing one first die cavity 41 on the mould and being located at the first die cavity chamber.During injecting glue, can adopt manual injecting glue device 3 to carry out injecting glue, this manual injecting glue device 3 comprises the syringe 31 that liquid-state silicon gel 38 is housed, the seal cover 32 of being located at the syringe top and the pin mouth 33 of being located at the syringe bottom, be connected with tracheae 34 on the sealing lid 32, this tracheae 34 is communicated with source of the gas, source of the gas, utilizes air pressure to promote pistons 36 motions in the syringe 31 and liquid-state silicon gel 38 is injected second die cavity to syringe 31 air feed by tracheae 34.In order to regulate the air pressure size in the syringe and the switching of control air pressure, on the sealing lid 32 air pressure adjustment switch 37 is installed also.When needing to inject silica gel, the syringe of required color liquid-state silicon gel is equipped with in selection, and this liquid-state silicon gel is injected in the second corresponding die cavity, finishes the injecting glue operation to five second die cavities in turn, shake entire die then, the soft phenomenon of silica gel when avoiding injecting glue occurring.After liquid-state silicon gel injected and finishes, the solid-state silica gel of can packing in first die cavity 41 passed through the hot-forming required silica gel push-button that promptly gets then.
In order to adapt to the production in enormous quantities of silica gel push-button, this injecting glue process can also realize by automatic injecting glue device.To shown in Figure 10, this automatic injecting glue device 4 comprises syringe 41 and the upset cylinder 42 that liquid-state silicon gel is housed as Fig. 8.The top of this syringe 41 connects source of the gas by first tracheae 43, and this source of the gas makes in the syringe 41 and remains pressure state.This upset cylinder 42 has valve body 421 and turnover spool 422, this valve body 421 has first interface 423 and second interface 424, the bottom of this syringe is installed in first interface 423 of valve body, pin mouth 45 is installed in second interface 424 of valve body, and spool 422 is located between this first interface 423 and second interface 424.Second tracheae 46 and the 3rd tracheae 47, the second tracheaes 46 and the 3rd tracheae 47 also are installed on this valve body 421 control the upset of spool 422 by in turn air inlet and exhaust.When starting working, 46 air inlets of second tracheae, 47 exhausts of the 3rd tracheae, spool 422 separates first interface 423 and second interface 424, and the silica gel in the syringe 41 can not outpour.When the needs injecting glue, 46 exhausts of second tracheae, 47 air inlets of the 3rd tracheae, spool 422 overturns under gas pressure and is communicated with first interface 423 and second interface 424, and the liquid-state silicon gel in the syringe outpours under the effect of air pressure.In the injecting glue process, compile and edit a routing sequence according to the position of injecting glue, the color and the injecting glue amount of requirement, silica gel push-button processing can realize full automation.In the present embodiment, spool overturns between the primary importance and the second place under air pressure control, and when primary importance, spool disconnects glue injection channel; When the second place, spool conducting glue injection channel.
In the present embodiment, by liquid-state silicon gel and solid-state silica gel hot pressing one are formed silica gel push-button, so the working (machining) efficiency height of silica gel push-button is not easy to wear, and technology is simple, has reduced man power and material's cost, also can guarantee the quality of silica gel push-button simultaneously.Because each second die cavity of mould can inject the liquid-state silicon gel of different colours, so can make button character have multiple color, makes the electronic product with this button have individual character more.Because the button character on the silica gel push-button is hot-forming by liquid-state silicon gel, promptly whole character all is the silica gel material, so more wear-resistant.This forming method not only can the shaping mobile phone button, and can the formed automobile stereo set, the button on various calculator and the remote controller.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
